yes haha my title is kind of mis leading, BUT...someone please explain to me about gear ratios... like i have 3.73s what makes that different from 4.10s and 2.73s or wutever.......

Number of times the wheels turn for every time the driveshaft turns.

so my wheels spin 3 times once my drive shaft has spun 73 times?? huh im lost...

Nono, if your rear end ratio is 3.73 it's short for 3.73:1. So wheels spin 3.70 rotations while the driveshaft spins one.

edit: oops I am an idiot. It's the other way around.

Say you spin your wheel 1 turn and your driveshaft turns 3.5 times.
More than likely you have 3.55 gears.

My old rear (10 bolt), the driveshaft turned 3.37 turns, I knew it was a 7.5 rear, so it had to be 3.42's. Called the dealer, gave them the last 8 digits in my VIN and I was right (3.42"s)

So, the lower gear you have (ie:3.73's, 4.11's) the more turns your driveshaft will turn for ever 1 turn your tire spins.

This only works if you have a POSI, if you have an OPEN type, multiple the driveshaft turns by 2.

Close, wheels spin once for every 3.73 turns of the shaft.

Right. I knew that. It's been a long night.

ahh i see i see, thank you for clearing that up!!
